    Abstract - (Show below) - (Hide below)

    Defines a coulometric procedure to determine oxygen permeability of rigid and non-hydrogel flexible contact lens materials and oxygen transmissibility of rigid and non-hydrogel flexible contact lenses. Describes methods for measurements and defines the conditions in which measurements are taken. Does not apply to hydrogel materials or hydrogel contact lenses.
